Shedding light on the parasite communities and diet of the deep‐sea shark Deania profundorum (Smith & Radcliffe, 1912) (Squaliform: Centrophoridae) from the Avilés Canyon (southern Bay of Biscay)

Journal of Fish Biology, Volume 108, Issue 4, Page 1150-1169, April 2026.
Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Genome‐Wide Protein Interaction Analysis in Parasitic Gyrodactylus Flatworms–Fish Hosts System and Drug Target Identification

Advanced Science, Volume 12, Issue 45, December 4, 2025.
Genomic data offer a powerful tool for studying the molecular interactions between parasites and their hosts, but they remain scarce for parasitic monogenean flatworms. This study presents the first high‐quality phased genome assembly for monogeneans (Gyrodactylus kobayashii), and uses it to predict key interacting proteins between monogenean parasite ‐

The Role of the Middle East in the Biogeographical Dispersal of Host‐Specific Parasites: Monogeneans and Their Cyprinoid Fish Hosts

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study investigates the diversity and phylogeny of Dactylogyrus species in the Middle East, as well as uncovers the historical dispersal routes and biogeographical contacts of cyprinoid host species using their host‐specific parasites. Location The Middle East. Taxon Dactylogyrus (Dactylogyridae: Monogenea), Cyprinoidei (Cypriniformes).

Insights into mucosal and systemic immune responses of African catfish, Clarias gariepinus, to chilodonellosis: A natural infection study

Journal of Fish Biology, Volume 107, Issue 4, Page 1323-1334, October 2025.
Abstract A natural parasitic infection with the external ciliate protozoan, Chilodonella hexasticha, was recorded 3 days post‐transportation (PT) in the gills and skin of African catfish (Clarias gariepinus). Infected fish displayed behavioural changes and typical signs of infection.

Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Exploring Silver as an Alternative Treatment for Controlling Macrogyrodactylus congolensis Populations

Aquaculture Research, Volume 2025, Issue 1, 2025.
Monogeneans are ectoparasites that in high densities, can cause harm and even death to their hosts. Therefore, treatment methods are continuously evaluated. The current study aims to determine the LC50 of ionic silver and silver‐engineered nanomaterials (ENMs) (nAg) in the monogenean Macrogyrodactylus congolensis and report on the toxicological effects

Seasonal population dynamics of the monogeneans Quadriacanthus kobinensis parasitising Clarias fuscus in Pearl River, China

Helminthologia, 2016
This paper describes the population dynamics of Quadriacanthus kobinensis on the gills of Clarias fuscus following a field investigation from June 2012 to May 2013 in Pearl River, China. The results showed that in Q. kobinensis prevalence was highest (70.
